Blackmagic Forum

Hello community, hope everyone is good.

So, I don't know how to explain this the best but I'm going to try.

I have some footage recorded at 60 fps, when I preview it in Media PLayer or VLC it runs smooth. Now the weird parts start to appear when I import it into DR. A few things happen:

1) If I set the timeline to 60 and drag the footage there.. the playback gets a lot of framfrops or even frame sppeds?? (I dont know if that is thee right term but you can see the monitor of FPS jumps up to 65 - 67 fps while playing back) and the result is a non smooth playback of the video.

2) If I go to clip attributes and switch it to 24 fps, and drop it into teh 60 fps timeline, the video runs smooth, no drops 24 FPS full green light, BUT in slowmotion of course.

3)If i create a 24 frame timeline and drop the footage (60fps) as it its, the footage runs smooth at it's normal speed (but the monitor is showing 24 FPS green dot instead of 60)

I'm wondering if I'm doing somehting wrong or someone can assist me with this issue?


For the record Im running all the footage on a i9 processor 64gb ram and rtx2070 so I reckon hardware settings are not the problem.
Any how hope I was a little clear and I appreciate in advance your time.
Have a good day

Hi bror31,

I'm on an iMac Pro running Catalina (a beta developer version, but I try not to blame Apple first...).

As of yesterday I started an editing session with some new 60fps ProRes 422 1080p footage - and ran into the 'speed up faster than 60fps, and then freeze/pause to 'catch up', repeatedly every second or so throughout the clips.

I undid the few changes made since running an earlier version of 16:
- I'd created a new db in the library, and so I went back to an earlier project using previous footage from an older library
- I'd futzed with the video cards (2 eGPUs running on the TB3 ports + the 8G version of the internal card...); and so I returned the settings to 'auto' as before. Note: Resolve, Neat, and other apps have mixed success with the eGPUs, but I did not bother to remove them (yet)

Other than that - perhaps an update of the dev version of MacOS, or some odd interaction with storage... but I did speed test from the 10G direct attached (iSCSI) 30TB RAID (tvs-872xt) - and it still serves nearly 1TB/s.

2) and 3) present instances where not all frames are playing back, so they're not useful measures of how well your system is working.

You've neglected to mention the type of footage you're attempting to play and its resolution, so there's not much anyone can tell you. There are various strategies for reducing the strain on computer resources (60fps 4K h264, for example, is highly demanding), including reducing the timeline resolution and use of so-called Optimized Media, whose many options you can read about in the manual.

If you're working with cell phone footage, the best course is transcoding it at the outset to a codec better suited to editing.

Sorry I was not fully clear. I did mention the footage recorded was 60 p (59.94) 4k. When its 24 p it runs smooth.
I also forgot to mention I generated optimized media and I used 1/4 porxy, wich is a lot as I never had to use it before. Yet when I import that footage on a 24 p TIMELINE it doesnt look smooth, and it does not always drops frame but some times kind of adds??

You need to stop fooling with frame rates. If you're generating optimized media, don't put it on a timeline with a different frame rate from the underlying source media.

If it's 60fps, put it on a 60fps timeline. Does it play without issue or not?

I wish it was a mattehr of fooling with frame rates, but is not. I tried what you just propsed and I still get frame drops (let's be super clear, I added a 59.94 footage into a 59.94 timeline. And yes stil get framedrops, what is even more interesting I optimized the medio to a very LQ codec, and set proxys to 1/4 and still getting frame drops)
Also, I get framedrops even from the source monitor, I don't even need to drop it into a playback to see frame drops. But when I play the raw file in VLC it runs perfectly... Maybe that explains some more. Thanks!!

You will not get the same apparent performance in Resolve, as you do from a simple video player in Windows. Resolve has much more stringent playback requirements.

Anyway, playback of 4K 60fps video on a 4K timeline (you still haven't identified the format) is challenging for any hardware. If you can't succeed with optimized media either, and assuming you don't have disk access failures, something may be wrong with your master project preferences. I would first of all reduce timeline and monitoring resolution to HD, then ensure that frame rate, playback frame rate and monitoring frame rate are all the same.

Also uncheck system/user preferences "use GPU for scopes" and "use GPU for braw". You could also click the 3 dots in the program monitor and select "play all video frames".

If none of that works, transcode the footage to an intermediate format (DNxHR, Cineform) and see if that helps -- again, keeping preferences consistent with respect to frame rates and playback.

Hi

Do you have a clip we can test ?

Best,
Ole

Thanks again for all your replies. So I jsut did a quick clip and uploaded it. This is the link:

https://drive.google.com/open?id=1POkor ... klAiG-J2of


The timeline and monitor settings where always set to 1080, I never tried runing it in 4k.
So to clear a little more.
All the footage is recorded in a Panasonic GH5s .mov h264 codec. Resolve runs all the other framerates perfect. It jsut does that with 59.94 (as you can see in the video I was writing down and doing a lot of test of bit rate, frame rates and format to define what could be the issue.

Hi

Do you use free or studio and what version ?

Hi there! I use Studio Version

No playback problems here !

Thanks for trying.. I wonder what could be... K would have doubted of my pc specs, even tho they are quite high, but afetr trying a LQ optimized media and 1/4 proxy I think it has nothing to do with it.

What's the specs of your i9 cpu ?

Start over.

1. User only internal drives. Have a dedicated Media drive, and ideally a dedicated drive for Cache and Optimized Media. No network or removable drives. Nothing on C: but Windows and Programs.

2. Create a project/timeline at the correct frame rate. (59.94)

3. Generate Optimized Media using Cineform 12 bit at 1/4 resolution.

4. Make sure the Show All Frames option is checked in the Timeline Viewer menu.

5. Make sure Use Optimized Media if Available is checked in the Playback menu.

It is my belief if that doesn't work, you have a more fundamental system issue.

It's s 9900K

Okay, your rtx2070 graphics card has a cable right up to your screen and your i9 9900K built-in UHD Graphics 630 is disable in the bios ?

I wouldn't be able to tell.. I'm affraid my knowledge doesn't reach that far. I should mention it is all in a laptop and not a desktop computer

Okay, your problem is the Intel 630. Disable it in device manager. The other suggestions above may be useful for optimizing performance, though I wouldn't bother with the disk recommendations. I played your footage on a much less powerful machine, without dropped frames, from an SD card. Disk access doesn't appear to be an issue for you, or this footage, at present.

Okay, I am goingto find out how to do that! I really appreciate your help guys! Thanks you very much! I'll keep you posted!

So I went to device manager and under "displays adaptors" the only one visible is the RTX2070... is there another way to know if UHD Intel 630 is disabled?

All,

We just updated to version 2.2.011, and the 'fast forward and then stutter' problem is gone. Happy to have lost only a few days (in my case) - which I'm sure benefited our project by means of raising the tension a little bit...

Sorry to bother again, just seeing if anyone can give me some help.. I just recived again files from a phone in 59.94 mp4 very light... they run smooth in every player I drop them... the second I open them in Davinci, even the source monito... it is not smooth at all.. even if the source monitor says there are no frames dropped... it looks like it does. I tried in different monitors too, one with 30 hz refresh rate and the other with 60 hz refresh rate... and nothing... I have no clue what can be happening.

This is an update.. I recorded with my phone a little of whats going on, I think you can clearly see what's happening, no need to mention, but that video file is 8 bit and the size is 37 MB.... I really don't think is a pc specs problem.

The first part is playing it through the source monitor in DR, then I stop it and go to VLC player on the other monitor... as you can see the difference is massive... I'll appreciate any help.

PS: Forgot to mention, when I render that file in DR the output video runs very smooth in every player.




Wich makes things more interesting, is that if I set up the timeline in 23.976 and I drop the footage there, in the monitor of DR it runs smoothly but when I run the source monitor the original file, id doesn't.

This issue has been noted many times here. Cell phones record with variable frame rates, which Resolve can't work with. Transcode the clips to another format.

John I appreciate your help, but you are not getting the point. That file was not recorded with a phone.. I dont recall ssaying that at any moment.the video showing how it plays back on DR was. I appreciate you take time to give input, I really do, but I find it irrlevant, all of it. Thanks tho.

"I just recived again files from a phone in 59.94 mp4 very light... they run smooth in every player I drop them... the second I open them in Davinci, even the source monito... it is not smooth at all.."

As John has mentioned, Phones record with variable fps! Do us the favor ... get the free app: MediaInfo ... and show us specs. of the footage !

OKay, I see where the misunderstanding was there... sorry.. I'm not the best english speaker and all this technical wording really confuses me. What I meant to say is that the files where downlaoded into my phone and they where runing smothly there too... I did the youtube video from my phone, but was just shooting at the monitors of my pc. I can tell how that could have been misleading. My bad. I will anyhow, get an app, and send you the information of those files. Thanks again for the reply.

Ole just did as you suggested. I was expecting this results as the first video I shared was with a GH5s, but anyhow, here it is... I really don't know what can be causing it. If you see the video I linked of you tube youcan see how it runs smooth on VLC but not on the source monitor of DR or the Timeline. I even found a user in this forum with the same issue but noone replied a solution to him either... and yes he only experienced it with 59.940 fps frame rate.

Regarding the UHD 630 Intel.. here you can see the only Display I have is the RETX 2070


In this post, with better words, this user experiences the exact same problem:

viewtopic.php?f=21&t=108310&p=629135#p629135


UPDATE: Out of curiosty I treid to playback the same clip in the Color page.. .and even tho everything is set in 59.940 the color page plays it back at 30 fps...

Your GH5 recordings play smoothly on my Davinci resolve computer -
so your problems must be connected to your laptop! Which RTX 2070
disklay driver do you have installed?

Do you have a power cable on your laptop?

Is your Power Plan Settings in Windows 10 set to High Performance ?

Power settings

Go to “Control Panel” and then choose the “Hardware and Sound” option.
Head over to “Power Options” and you can see two options —
“Power Saver” and “Balanced.” Click on “Show additional plans” you
want the “High Performance” setting.

Switch off visual effects

Go to “System” and open the “Advanced System Settings.” Select the “Advanced”
tab and open the “Settings” option under “Performance.” To shut off all the
visual effects, simply check the “Adjust for best performance” radio button.
If you want, you can enable the “Smooth edges of screen fonts” option to read
text more easily.

Ole, thanks again for your input. I have to discard your options tho. I dont think is even close to be related to my laptop. The things you suggest to do, where done the first day I purchased it, and it always run through a cable. Adding more, I can't belvie it will only show that issue in DR and only at 59.94 fps (actually after writing that you gave me an idea.. I tried that footage on Adobe Premiere Pro and guess what?? plays smooth as butter) I also rendered some motion graphics from After efffects at 59.94 and imported them into Resolve... choppy again... while in AE plays excelent. So, is not the video codec, is not the pc specs (as it plays good in other NLES) wich leaves me thinking its DR, specially after fninding 5 different topics on this forum with people experiencing the same, and ONLY at 59.94 fps. Anyhow, I'll guess I just wait until more ppl starts to notice it and BM wants to adress the issue, or some user finds the solution... it's not that I'm dying to shoot at 59.94 fps anyway. Thanks again for all your input!

We both have the same Davinci Resolve Studio installed!

We both have the same GH5 footage!

My computer plays your 59.94 fps GH5 recordings without any problem - your computer cannot play your GH5 recordings at 59.94 fps!

And then you've come to realize that it's Davinci Resolve that is the problem?

Ole try not to get upset. We are ttrying to take this discussion as adults. You know that a lot of people Has DR and a lot of people has experienced problems on DR than others didn't? I keep reading issues in this post of people experiencing things on DR that I never experienced, and yet, we have the same DR. So yes, I think is DR, specially after trying all the thing I could think of, and trying all the things you suggested. Sometimes those things happen. If you dig in other topics, you'll realize it's not only "my"computer.
Anyhow I really appreicate your help!

"Ole try not to get upset. We are ttrying to take this discussion as adults."

Hmm, I think you've mistaken how I write - that's to eliminate problems - that one compares!

Why am I not experiencing the same problems with your recordings ?

"You know that a lot of people Has DR and a lot of people has experienced problems on DR..."

Yes, and many of these problems occur when people forget that 1080p 60fps is equivalent to dual HD
or UHD 30fps and does not have enough computer power to uncompress mp4 codes!

Ole I must have misunderstood the exclamation points.

Here, I did something that will put your theory off.
This is a Screen capture I did in FULL HD of my desktop, while runing DR and Premier Pro at the same time plus OBS recording, plus powering 2 monitors (I only recorded the main one) Ohhh, and My resolution is4k in both. If you really think after seeing this video that it's my (that you can clearly observe how it handles 2 NLES a Screen recorder, and how SMOOTH plays on Premiere), instead of reading other topics with the same issue, I'd say that your input is not what I need anymore. And again, thanks for takign your time to reply.

"I'd say that your input is not what I need anymore"

Are we still trying to take this discussion as adults ?

What is your theory about that I have no problem playing your recordings ?

Ole Kristiansen wrote:"I'd say that your input is not what I need anymore"

Yes, of course I am, hence I would stop taking your advices as none seems to work, but thanks.

I don't have a theory why you don't have problems. But I've proven your theories thowards my set up to be wrong. Thanks onces more for your time. If you come with relevant information or ideas to help me solve the issue, I'd appreciate them. If they are related to my setup, I won't find them useful, so again, is not the input I'll need.

"I'd appreciate them. If they are related to my setup, I will not find them useful, so again, is not the input I will need"
How to know ?

You forgot to tell that you had a laptop .... you didn't write about changes power plans......no one knows which display driver you are using.... ect.

"How to know"

Just by the simple fact that you are ignoring 5 other topics with the same issues and you are just fixated (like a kid trying to prove a point) on my setup. Hence, I think we should stop this and focus on DR not playing 59.94 porperly on, not only mine, but other users "different" setups (pc's and laptops). Let's just stick to that please. I know how powerful my laptop is.

Now stop all that crap about how I am ... it will not help with your problems !

In Davinci Resolve can you go in Preferences and show a picture of Memory and Gpu settings! Maybe Premiere uses your cuda cores and your settings in davinci Resolve are wrong! I have a AMD card so you can not use my settings !

Hmmm I'd say pretty much the same, just different card but Im on CUDA instead of OPEN CL... Im gonna try to set Open Cl and see what happens

Please start again.
As per the FAQs, detail your system.. everything.
Is it a laptop?
What monitor is being used?
Are you on 16.2.2?
Free or Studio?
Which GPU driver is installed.
Is the intel GPU disabled in windows?
Is the use display GPU off?
What do you have set for timeline frame rate and res?
What is the source clip codec, res and frame rate? (i havent looked at your file)

As others play that file ok its sounds like a system setup you have but we need the facts to avoid 10 guesses.
Everyone wants to help but there are so many missing elements.

Peter thanks for your reply. Let’s see if we can get to the bottom of this.
I’m gonna put together all my research and test so far in this post.

Issue: Tried different footage from different cameras, all recorded at 59.94. All of them run choppy at DR (either the source monitor, or timeline) but it runs perfect on any media player, or even in Adobe Premiere Pro.
I also rendered a Motion Graphic in AE at 59.940 and it played smoothly on AE, but same issue happened on DR.
First link I’m attaching is a video recorded with OBS where it shows very clear the performance on each software (that is not a GH5s footage, but I am attaching also a screenshot containing all the relevant info of the source clip codec I’m using as demonstration, but it happened with different codec videos, all of them at 59.940) :



Here is a screenshot of the source clip codec:






Now I’m going to proceed to my laptop specs:

i9 9900 K 3.5 GHZ
64 GB RAM
RTX2070
SSD Evo 860 2 TB
SSD nvme m.2 512 GB
The laptop is optimized for performance, and it’s always used with cable current I disabled all the power saving modes.
I tried the playback con an Acer Predator 4k, the built in screen of my laptop, and a HD Acer external monitor. (I also tried the 30 and 60 hz)
Needles to say, but I will anyway, that I tried also rendering the lowest quality of optimized media, and quarter of a proxy (wich it should run super smooth with my laptop specs, but again, not at 59.940) I have to insist that this only happens in Da Vinci Resolve, and ONLY happens with the 59.940 resolution. If it helps, I noticed it happens the most in PANS OR TILTS.

The settings on the timeline and project of DR are all set to 59.94 (as you can see on the video)
I am running the latest version of Davinci Resolve, and its the Studio version.

The UHD GPU 630 is Disabled.

I am now attaching also a screenshot of the nVIdia driver installed (wich says is the latest one too)




Now when it comes to others playing the file ok, I have no clue why, but I took the time to search and link for you all the other topics of users experiencing the same issue I experience.
Please note that all of them have the issue at 59.94 only, here the links to every single topic I could find (as you can see their setups are not only laptsp, one of them even experiences it on a Quadro Graphic card)

viewtopic.php?f=21&t=105097

viewtopic.php?f=21&t=108310


viewtopic.php?f=21&t=104974

viewtopic.php?f=21&t=89560

I think that is a lot of info, but if you require something else, please make me know and I will provide it. Thanks you very much.


I think that replies all your questions, the only one I couldn’t understand is:
“Is the use display GPU off?”
If you can point me that I can try it too.

EDIT: When the video is played in the Color Page, despise having all set at 59.940, it plays half speed and it shows 30 fps.

Thanks again.

You removed the sample file from the gdrive link - I was going to test it on my setup just to see how it performed...
